AUTOMATIC FELT-GUIDE FOR PAPER-MACHINES.

SPBCIFIGATIO N forming part of Letters Patent No. 296,222, dated April 1,1884.

(No model.

To all whom it may concern:

Be it known that I, BENJAMIN A. Sono- BIGER, of Montoursville, in the county of Lycoming and State of Pennsylvania, have invented a new and Improved Automatic Felt Guide for Paper-Machines, of which the following is a full, clear, and exact description.

My invention consists of certain improvements in that class of devices whereby the felts of paper-machines will be automatically corrected when tending to run sidewise or out of line in consequence of the tension of the web varying by the stretching of some parts more than others, as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a front elevation of my improved regulating apparatus with some parts in sec- One of the rolls a, over which the felt 2) passes with sufficient pressureto cause the roll to revolve, is mounted in bearings a, carried on a plate, (Z, that is fitted on a pivot, e,

under the center of the roll, on which the roll may swing horizontally, and above the roll is a rod, f, having a cone, 9, fitted on it near each end, which cones rest at their larger ends on the roll c, while the ends of the rods extend into the slots of the bearing-supports c of the roll a, to hold said rod in its position on the roll. The cones are adjustable along the rod by nuts t, to set them as may be required for wide or narrow felts. If the felt runs crooked, and thus shifts to one side or the other, the edge will, by running into the gradually-diminishing space between the cone and the roll, be caused to draw harder on the roll that side of the center by drawing under the cone, which will turn the roll-sup ports on the pivot e, and so incline the roll a that it will guide the felt back to its true course, and thus the edges of the felt will be prevented from running against any object that will damage them, and the forcing of the felt back to its true course by a roll moved by handscrews, and the running of the edges of the felt over to and against the frame will be avoided.

The bar d is provided with carrying-rollers h, to take the weight off the center bearing,

and also to support said bar near the ends, to prevent it from springing, and near the end said bar has stopchains j attached, which are connected to the platform suitably for limit ing the swing of the roll beyond the necessary limit.

The center bearing for the support of the bar (2 consists of a base-plate, m, of metal, having a couple of annular flanges, is, near the center on the upper side, with which similar flanges, Z, of the under side of another plate, 0, fit, the plate in being attached to the board which is mounted on the base of the machine, and the plate 0 is attached to the under side of the bar d; but said center bearin g may be constructed in any approved way.

The improved automatic guide works equal- 1y well on a second-press felt, on a drierfelt, or Fourdrinier wire, as on a firstpress or web felt, and effectually protects them from all damage, such as theyare subject to in the use of fixed or any other guides that allow the edges to run against the frame.

I am aware that felt-guides for paper-machines have been mounted in a swiveled frame,

said guides consisting of a rod extending from one vertical arm of the frame to the other above the roll, and provided with adjustable cones at both ends within the uprights; also, that two rolls have been mounted on screwthreaded rods on a similarly-constructed frame above the rollers, the play of the latter frame being limited by upwardly-projccting rods mounted below said frame.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is 1. The guide-roll a and cone-guides g, in combination with a paper-machine felt, b, and mounted on a supporting-bar, (I, having a center pivot, e, and carrying-rolls h on opposite ends of the bar for supporting said ends, substantially as described.

2. The guide-roll c and cone-guide g, in combination with a paper-machine felt, I), and mounted on a supporting-bar, (1, having a central pivot, e, carrying-rolls 71; on opposite ends of .the bar, and stop-chains 7', whereby the ends of the bar will be supported and the play of the bar limited, substantially as described.

3. The combination, withthe roll of a paper-machine carrying a felt, and said roll being mounted in a swivcled frame, of a rod having screw-threaded ends and mounted in said frame above the said roll, and carrying cones adapted to bear upon the felt passing over the roll, and nuts on the rod at each end of the cones for securing said cones in place, substantially as specified.

4. The combination of the frame supporting the guide-r011 and cone-guides, and having the rollers h h on its inner side at each end, and thecentrally-perforated flanged plate 0 Z, I 5 with the base or frame 1) q, provided With the centrally-apertured and flanged plate m k, the flanges of the plate on fitting Within those of the plate 0, and a connecting-pivot, 6, sub stantially as set forth.
